Abstract

La présente invention se rapporte à un séparateur bipolaire destiné à des assemblages de piles à combustible à membrane polymère, qui est défini par deux feuilles dotées de trous de passage de fluide, qui sont reliées par l'intermédiaire d'un élément ondulé et possèdent une section permettant le passage d'un liquide de thermostatisation. Ainsi, l'invention permet un retrait de chaleur des piles adjacentes, ainsi que l'humidification et la distribution des gaz, à l'aide d'une pièce intégrée unique, et par là même une simplification de l'ensemble et de l'étanchéisation hydraulique de l'assemblage.
